What If We Dug a Hole Through the Center of the Earth?

Imagine you have a giant straw going straight from one side of the Earth to the other. If you jumped in, gravity would pull you down toward the center, like being on a roller coaster. Once you pass the center, you'd start floating up again because gravity is now pulling you in the opposite direction. You’d keep moving back and forth until something slowed you down.
